1-32 Series Power Battery Protection Board BMS Testing Machine
It is mainly used to detect whether the functional indicators of the power battery protection board are within the parameter range, so as to provide a set of detection standards for the staff. It is mainly used for testing power battery protection board of protection board manufacturer and power battery manufacturer.
Quick Test:According to the design parameters of the protection board, the test parameters are set to carry out the rapid test, which is convenient for the protection board manufacturers and power battery manufacturers to carry out large-scale rapid test and shipment. At the same time, it is suitable for the protection board test of various hardware schemes and some software schemes.
Routine Test Items:
Internal resistance test, overcharge and overdischarge test, overcharge recovery, overdischarge recovery test, over-current test (charging and discharging over-current), overcharge protection voltage, overcharge recovery voltage, over discharge protection voltage, over discharge recovery voltage, over-current protection, etc.
Special Test Items:
Short circuit protection test (refers to the real short circuit protection test microsecond level).
Single section self consumption test (refers to the true and accurate self consumption of each section).
Equalizing current and equalizing voltage (it can accurately grasp the equalizing current and equalizing opening voltage).
High Current Module:The current level is 150A and the current accuracy is 0.1A.
